CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. patent application Ser.
No. 11/873,288 (filed Oct. 16, 2007) as a continuation in part thereof.
The above identified application is hereby incorporated by reference.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

[0002] N/A

BACKGROUND OF THE INVENTION

[0003] 1. Field of Invention

[0004] The present application is in the field of apparatus for dispensing
cosmetic substances.

[0005] 2. Background of the Invention

[0006] The ideal cosmetic dispenser is non-messy, portable, capable of
storage, rapid delivery and easy application of a cosmetic substance.
Typical cosmetic dispensers have a substance compartment whose contents
may be emitted or placed onto an applicator for cosmetic application.

[0007] Ordinarily, cosmetics dispensers come equipped with a detachable
lid or cap that is pulled or twisted off from the dispenser to expose the
applicator. The purpose of the lid is to protect the applicator from
outside corruption and prevent unintentional transfer of substance away
from the applicator. One problem with this type of dispenser is that a
contained substance can be wasted through inadvertent expulsion into the
lid. Another problem with this type of dispenser arises through unmindful
removal or replacement of the lid over the applicator since the substance
invariably smears to the outside or the attaching portion of the lid.
When this happens, subsequent lid removal becomes increasingly difficult
and the cosmetic substance unwittingly dirties the dispenser user's
hands. It is also difficult, with the traditional dispenser to maintain a
sanitary applicator. Another drawback for this type of dispenser is that
it requires two hands to remove the lid. Yet another problem is that the
removable cap can easily be lost.

[0008] Cosmetic dispensers typically have some method to accomplish
substance expulsion. Ordinarily, expulsion is triggered by manually
twisting a driver, or by squeezing the compartment. However, twisting is
undesirable because it takes two hands and is time consuming. Squeezing
is undesirable because the amount of substance emitted is not easily
metered, and can lead to substance waste because squeezing does not
easily remove all the substance from the containing compartment.

SUMMARY OF THE INVENTION

[0009] Accordingly, it an objective of the present application to provide
a cosmetic dispensing apparatus featuring a retractable applicator that
permits elective exposure or concealment of the applicator.

[0010] It is a further object of the present application to provide a
dispensing apparatus which allows elective expulsion of a substance while
the applicator is exposed.

[0011] It is yet a further object of the present application to provide a
dispensing apparatus without a detachable lid or cap, but which apparatus
still protects the applicator from outside corruption.

[0012] It is yet a further object of the present application to provide a
dispensing apparatus which may be used sufficiently with one hand.

DETAILED DESCRIPTION OF PREFFERED EMBODIMENTS

[0049] The dispenser 101 of the present application usually has an
enclosure capable of containing substances and a suitably placed
applicator 117 which acts as avenue from an enclosure to an applicator
tip 118. Additionally, there is typically a means for inducing movement
of the stored substance along the applicator shaft 115, culminating with
expulsion of contained substance through an applicator tip 118. The
applicator 117 (usually featuring an applicator tip 118 and an applicator
shaft 115) of this dispenser 101 is suitably retractable, or extendable,
and operationally configured to be concealed internally until electively
exposed for use, and then electively re-concealed.

[0050] FIG. 1 depicts a dispenser 101 in a closed configuration. The
figure shows a dispenser body 103 featuring a slit 111 preferably
situated around a lever 107, which lever 107 suitably defines an
excrescence on the dispenser body 103. FIG. 1 also shows the anterior of
the dispenser body 103 suitably occupied by a cap 105 and cap housing 122
which may variably seal the anterior opening 102 of the dispenser 101.
The posterior of the body 103 is suitably occupied by a plunger 109 that
typically coaxially merges into (or with) the body 103 by way of the
posterior opening 104. In FIG. 1, the plunger 109 represents a
deactivated trigger and the anterior opening 102 represents an exit
location for the applicator 117. As detailed below, the lever 107 is an
inactive reversion means, meaning that it may function to release the
applicator 117 from a fixed extended position, allowing it to be
selectively retracted by the user into the body 103 of the dispenser 101
(as depicted in FIG. 1). Also detailed below, in FIG. 1 the cap housing
122, body 103, and plunger 109 have various internally concealed
components.

[0051] FIG. 2A typifies a dispenser 101 in an open configuration. The
figure illustrates a cap 105 held open and away from anterior opening 102
by a pair of rigid, yet flexible, cap shoots 110 and a flexor 113. FIG.
2A also depicts the protrusion of an applicator 117 through the exposed
anterior opening 102. An activated lever 107 is accessible at slit 111,
and a partially depressed plunger 109 extends from the posterior opening
104. In FIG. 2A, the anterior opening 102 is the exit location for
applicator 117. As detailed further below, the lever 107 is suitably an
activated reversion means because interaction therewith may result in the
reversion of the dispenser into the closed configuration depicted in FIG.
1. Also detailed below, in FIG. 2A the cap housing 122, body 103 and
plunger 109 have various internal components.

[0052] Referring to FIGS. 1 and 2A, the dispenser 101 of the present
application has a suitably retractable applicator 117 which may be
electively exposed for applicator tip 118 use. Elective transition from a
closed to an open configuration is usually achieved through application
of an initiating force which suitably activates the plunger 109 as a
trigger, exposes anterior opening 102, and protrudes the applicator 117
from the dispenser 101. In most instances, the acting force on the
plunger 109 will be generated by the user manually, for instance by a
thumb or finger. The dispenser 101 typically has a natural tendency to
revert from an open to a closed configuration. As discussed further
herein, during transition from closed to open configurations, this
tendency is normally continuously opposed to applicator 117 protrusion
and plunger 109 activation.

[0053] However, once the plunger 109 has been activated, the applicator
117 is suitably locked in external position and natural reversion of the
dispenser 101 to a closed configuration is prevented. Also discussed
further herein, once the dispenser 101 is suitably locked into an open
configuration, the lever 107 suitably becomes an activated reversion
means which may electively be acted upon to release the lock, thereby
enabling the aforementioned natural tendency to actuate reversion to a
closed configuration. FIGS. 1 and 2A taken together may help visualize
this transition. Referring to these two figures, when an external axial
force is applied to the butt of the plunger 109 in FIG. 1, such force
depresses the plunger 109, extrudes cap shoots 110 from cap housing 122,
releases the cap 105 along flexor 113, and projects applicator 117 from
the anterior opening 102. Once the force moves the plunger 109 to its
partially depressed position in FIG. 2A, plunger 109 and lever 107 are
activated and the configuration is usually locked in place. At this
point, reversion to the closed state of FIG. 1 normally can only be
attained through interaction with lever 107. See the discussion below for
more details.

[0054] FIG. 2B depicts a dispenser 101 in an open and dispensing
configuration. The FIG. 2B configuration is suitably necessary for
expulsion of contained substance through an exposed applicator tip 118.
As seen in the figure, a dispenser 101 in such an open and dispensing
configuration has components in roughly the same relative positions as
that of FIG. 2A, but the plunger 109 is suitably depressed fully toward
the body 103. In other words, the depressed and active plunger 109 may be
typically used as an active trigger to forcibly eject cosmetic substance
from an applicator tip 118 of the dispenser 101.

[0055] Transition from an open (FIG. 2A) to an open and dispensing (FIG.
2B) configuration is usually accomplished by a motive force placed upon
the contained substance. The motive force may preferably be caused by the
plunger 109 being fully depressed and active. A fully depressed and
active plunger 109 typically results from axial impulse on the end of the
activated plunger 109 (FIG. 2A). As discussed in more detail below, this
impulse preferably induces metered dispensing of a contained substance
from the exposed applicator tip 118. Applicator 117 may feature at least
one, or a plurality of orifices through which substance may be expelled.
Dissipation of the aforementioned impulse results in reversion of the
plunger 109 from fully (FIG. 2B) to partially depressed (FIG. 2A) and
suitably ends dispensing of substance until a new impulse is triggered.
Usually there is no mechanism to lock the dispenser in an open and
dispensing configuration. FIGS. 2A and 2B together may help visualize
this process. Referring to these two figures, when an external axial
impulse is applied to the butt of the plunger 109 in FIG. 2A, this
impulse usually fully depresses the plunger 109 to its position in FIG.
2B which induces metered expulsion of a contained substance from
applicator tip 118. Upon dissipation of the axial impulse, the fully
depressed plunger 109 of FIG. 2B preferably automatically returns to its
position in FIG. 2A. A typical use cycle would entail impulsive
depression of the plunger 109 from its partially depressed position in
FIG. 2A to a fully depressed position of FIG. 2B, followed by reversion
to its partially depressed position in FIG. 2A. Normally, the cosmetic
dispensing feature of dispenser 101 is accomplished by the plunger 109
being cycled repeatedly to cause sufficient accumulation of contained
substance at the applicator tip 118, where a user would then apply the
substance to the lips, eyes, face, or the like.

[0056] Still referring to FIGS. 2A and 2B, the specifics of the applicator
117 (usually including the applicator shaft 115 and applicator tip 118)
depend on the type of substance and the nature of the dispenser 101
purpose. In the accompanying figures, the applicator 117 is a hollow
truncated cylinder with an angled cylindrical section as the applicator
tip 118 surface, as one might see in a lip gloss applicator. In some
instances, however, the applicator tip 118 may just be an orifice or
other type of opening through which a substance may be discharged. In
another instance, the applicator tip 118 may be a membrane through which
substance may be expelled. In yet another instance, the applicator tip
118 may be some type of rigid member to which expelled substances may
adhere while awaiting application (e.g., a brush for mascara).

[0057] FIG. 3A (FIG. 5 is an enlarged view) is a longitudinal
cross-section of the dispenser 101 of FIG. 1. (since the components are
depicted in cross-section, the specific features of the internal
components are better viewed in FIG. 4 which is an exploded view of the
dispenser 101). The figure shows a dispenser 101 with a closed cap 105
and body hollow 106 which houses the applicator 117 including the
applicator shaft 115 and applicator tip 118, the retraction spring 119,
the cap shoots 110, the shoot press 124, the contracted arm 116, ledge
112, a movable reservoir body 127 (which contains the piston 125, and
part of the plunger shaft 121), resistor 126, drive gear 129, and crank
130. The figure also shows a dispenser 101 with a plunger cavity 108 that
houses the plunger spring 123, the crank housing 140, and most of the
plunger shaft 121, drive gear 129 and crank 130. In FIG. 3A the plunger
109 is fully extended away from the body 103 and the internal components
of the body hollow 106 are toward the body 103 posterior. The reservoir
body 127 and its chamber 128 are an enclosure configured to contain
cosmetic substances, which are usually fluid or powder in nature. Typical
substances include, but are not limited to, lipstick, mascara, lip gloss,
blemish remover, concealers, eyeliners, and the like as will be
appreciated by those skilled in the industry. The applicator shaft 115
suitably defines an avenue or channel between the applicator tip 118 and
the chamber 128 containing substance. In other words, the applicator
shaft 115 and chamber 128 are suitably in fluid connection with one
another

[0058] FIG. 3B (FIG. 6 is an enlarged view) is a longitudinal
cross-section of the dispenser 101 of FIG. 2A (since the components are
depicted in cross-section, the specific features of the internal
components are better viewed in FIG. 4 which is an exploded view of the
dispenser 101). The figure illustrates the following components: a cap
105 held open and away from anterior opening 102 by a pair of rigid, yet
flexible, cap shoots 110 and a flexor 113; and, applicator 117 (which
usually includes applicator tip 118 and applicator shaft 115) protruding
through exposed anterior opening 102. The body hollow 106 houses the
retraction spring 119 which is compressed against the spring stop 120;
the shoot press 124 which has pushed the cap shoots 110 through the cap
housing 122; the arm 116 extended to the ledge 112; and the reservoir
body 127, which is locked in its position and which contains the piston
125 and part of the plunger shaft 121, resistor 126, drive gear 129, and
crank 130. The figure also shows a dispenser 101 with a plunger cavity
108 that houses the plunger spring 123, idle plunger shaft 121, resistor
126, drive gear 129, and crank 130. In FIG. 3B the activated plunger 109
is more depressed toward the body 103 than the deactivated plunger 109 of
FIG. 3A and the internal components of the body 103 hollow 106 are more
toward the body 103 anterior.

[0059] FIG. 3C is a longitudinal cross-section of the dispenser 101 in a
open and dispensing configuration (since the components are depicted in
cross-section, the specific features of the internal components are
better viewed in FIG. 4 which is an exploded view of the dispenser 101).
FIG. 3C is the same as FIG. 3B except the figure shows a dispenser 101
with a fully depressed plunger 109 and plunger cavity 108 which houses
the compressed plunger spring 123, the working plunger shaft 121,
resistor 126, piston 125, drive gear 129 and crank 130. In FIG. 3C the
plunger 109 is more depressed than the plunger 109 of FIG. 3B.

[0060] As mentioned above, a dispenser 101 transition from a closed to
open configuration is opposed by a natural tendency to remain in, and
revert to, a closed configuration. FIGS. 3A and 3B provide an
illustration of such a natural tendency.

[0061] These figures show a dispenser 101 with a retraction spring 119.
FIG. 3A depicts the retraction spring 119 while the dispenser 109 is in a
closed configuration. In transitioning from the dispenser 101 of FIG. 3A
to that shown in FIG. 3B, after the cap 105 has opened, the applicator
117 suitably protrudes through the anterior opening 102 and the
retraction spring 119 partially compresses against spring stop 120, which
causes a continuous opposing force to the applicator 117 protrusion.
Plunger 109 is activated by depression from its position in FIG. 3A to
its position in 3B, which plunger 109 depression accomplishes at least
the following: (1) moves the reservoir body 127, shoot press 124, and arm
116 toward the anterior; (2) extrudes the cap shoots 110 through cap
housing 122 to open cap 105, and guided by flexor 113; (3) drives the
applicator 117 protrusion; and, (4) suitably compresses the spring to its
position in FIG. 3B. The force of compressed retraction spring 119 is
constantly opposed to plunger 109 activation and applicator 117
protrusion.

[0062] Though the figures depict retraction spring 119 as the natural
tendency, an internal compression spring is not the only means for
inducing the aforementioned natural tendency. Such natural tendency may
be invoked internally or externally through the use of magnets, elastics,
rubbers, manual or any other attractive or repulsive force.

[0063] As mentioned above, until dispenser 101 is locked into the open
configuration, the natural tendency will suitably invoke reversion to a
closed configuration. The dispenser 101 of the present application
typically uses a suitable latching means to lock the open configuration
when the applicator 117 has been protruded sufficiently from the anterior
opening 102. The latching means may remove the natural tendency or
suitably counteract the force. FIGS. 3A and 3B provide illustrations of a
latching means in operation. FIG. 3B depicts an arm 116 extending from
the reservoir body 127 that fixes to a ledge 112 notched into an inner
wall of the body 103 just below the slit 111. FIG. 3A shows this arm 116
contracted while the dispenser 101 is in a closed configuration.
Application of an axial initiating force at the plunger 109 butt,
depresses the deactivated plunger 109 of FIG. 3A, and moves the arm 116
toward ledge 112 below slit 111. FIG. 3B shows arm 116 levered against
the ledge 112 such that compressed retraction spring 119 cannot expand to
force the dispenser 101 to a closed configuration.

[0064] Though the figures depict extended arm 116 and ledge 112 as the
latching mechanism for dispenser 101, there are many other suitable
latching means. This latching means might take the form of a hook, lever,
constriction, latch, adhesive, friction, and by other means that would be
appreciated by those skilled in the art.

[0065] The plunger 109 becomes an activated trigger when further
depression accomplishes expulsion of contained substance from the exposed
applicator 117 at the applicator tip 118. To prevent undesired and
unintentional internal ejection of contained substance at the applicator
tip 118, the plunger 109 is not used to eject substance until the
dispenser 101 is in the open configuration. FIG. 3A and 3B provide an
illustration of plunger 109 activation. As mentioned above, the
deactivated plunger 109 of FIG. 3A may be depressed by an initiating
force until extended arm 116 meets ledge 112 to lock the dispenser in its
FIG. 3B configuration. Beginning at FIG. 3A, an initiating force applied
to the butt of deactivated plunger 109 moves at least one of the
reservoir body 127, shoot press 124, and contracted arm 116 from a
posterior position to an anterior position as seen in FIG. 3B. During
depression, the retraction spring 119 compresses against spring stop 120,
the cap shoots 110 extrude out of the cap housing 122, the cap shoots 110
force open the cap 105 while the flexor 113 guides the cap 105 away from
anterior opening 102, and the applicator 117 (which usually includes
applicator shaft 115 and applicator tip 118) protrudes from the body 103
and cap housing 122 through anterior opening 2. When locked in this open
configuration, the plunger 109 is activated because further plunger 109
depression induces substance movement along applicator shaft 115
culminating with ejection through the applicator 117, suitably by way of
the applicator tip 118.

[0066] A lever 107 becomes an activated reversion switch when action upon
it results in reversion from an open to closed configuration. A lever 107
as a reversion switch is a suitable means for unlocking the open
configuration. FIG. 3A and 3B illustrate the activation of a lever 107 as
a reversion switch. In FIG. 3B, arm 116 interacts with ledge 112 just
below the slit 111 to prevent retraction spring 119 from expanding from
its compressed state. While arm 116 is interacting with ledge 112, lever
107 deflection is required to dissociate the arm 116 from the ledge 112
and thereby effectuate reversion of dispenser 101 to a closed
configuration. Importantly, the protuberance 114 is usually designed to
allow smooth transition from a closed dispenser 101 configuration to an
open configuration and vice versa. In other words, the protuberance 114
does not usually extend distally from the arm 116 to a degree or to the
extent that would allow the protuberance 114 to interact with the other
internal components or features of the dispenser 101 in a manner that
blocks or hinders transition between dispenser 101 configurations.
Rather, the protuberance interacts with the internal surface of body 103
to prevent the distal end of arm 116 from snagging thereon while
contracted. In the open configuration, the lever 107 of FIG. 3B is an
activated reversion switch because acting on it contracts arm 116, and
allows retraction spring 119 to push the exposed applicator 117 (which
usually features an applicator shaft 115 and an applicator tip) back
within the body to the FIG. 3A configuration. The lever 107 in FIG. 3A is
inactive because acting on it does not result in reversion. Finally, as
mentioned above, lever 107 suitably defines an excrescence on the body
103 in order that lever 107 may be more readily identified whether by
sight or feel. However, the degree or extent of desirable excrescence
will vary and change depending on desired dispenser 101 use and in some
instances a lever 107 may be flush with the body 103 surface and not
define an excrescence at all. Such details will be apparent to those
skilled in the art. Though the figures depict the lever 107 in
association with slit 111 as a reversion switch, anything that releases
the dispenser 101 latching means may be used as a reversion switch.

[0067] Another feature of the dispenser 101 is the cap 105 which, in
conjunction with an elastomeric spring stop 120 and the applicator shaft
115, electively seals or unseals the anterior opening 102, typically by
way of a substantially air or water tight pocket. FIGS. 1, 2A, 3A and 3B
(and FIG. 4 for views of the internal components) provide an illustration
of the cap 105 in operation. While dispenser 101 is in a closed
configuration like that of FIGS. 1 and 3A, the cap 105 suitably seals the
anterior opening 102 of the dispenser 101 as follows: the retraction
spring 119 is fully extended and preferably forces the shoot press 124 to
abut the reservoir body 127 at one end, and the presses the spring stop
against cap housing 122 on the other end; the shoot press 124 suitably
pulls the cap shoots 110 taut, which tension usually interlocks the cap
105 with the cap housing 122 and secures the cap 105 over the anterior
opening against the anterior of spring stop 120; the tension on the cap
shoots 110 between the shoot press 124 and the cap 105 suitably squeezes
the spring stop 120 between the cap 105 and the cap housing 122 thereby
forcing deformation of the elastomeric spring stop 120 until the anterior
opening 102 is substantially air or water tight; and finally, at the
posterior of the spring stop 120, the applicator shaft 115, which is
coaxial to the spring stop 120 and which has an increasing diameter
toward the applicator 117, forces deformation of the posterior of the
spring stop 120 by way of its increasing diameter relative to the
diameter of the spring stop 120 (see FIG. 3A). Accordingly, a
substantially air or water tight pocket is created between the cap, the
spring stop 120 and the applicator shaft 115. Other sealing means
preferably may be placed throughout the dispenser 101 to effectuate an
optional air or water tight dispenser 101. As illustrated by FIGS. 3A and
3B, to unseal the cap 105, plunger depression moves the reservoir body
127 and shoot press 124 internally toward the anterior opening 102, the
shoot press forces the cap shoots 110 through the cap housing 122, and
the cap 105 is forced off of the anterior opening 102 by the cap shoots
110 and drawn away by the flexor 113. Also, as the tip 118 is exposed
from anterior opening 102, the decreasing diameter of the applicator
shaft 115 relative to the posterior of the spring stop 120 permits the
elastomeric spring stop 120 to return to equilibrium (see FIGS. 3B or
3C). A substantially air or water tight pocket at the anterior opening is
useful to prevent contamination, corruption, or dehydration/drying of the
tip 118 and contained substance. Additionally, attached to distal end of
the flexor 113 is a hook which interacts with cap housing 122 to extend
the useful life the seal. The flexor 113 slides forward with the cap
shoots 110 when the plunger 109 is pressed, and the hook stops at the
base of the cap housing 122 when the cap is open as illustrated in FIGS.
3B and 3C. This feature typically allows the cap 105 to come down evenly
on the seal surface of spring stop 120 without applying to much pressure
to one side of the elastomeric spring stop 120 and possibly deforming it
over time.

[0068] The dispenser 101 of the present application normally ejects a
substance through the exposed applicator 117 at the applicator tip 118
after an impulse has sufficiently depressed a plunger 109 and induced
movement of a contained substance along an applicator shaft 115 between
the applicator tip 118 and the chamber 128. Movement of said contained
substance along the applicator shaft 115 may be realized by a piston,
pump, suction, expansion, compression or otherwise as will be appreciated
by those skilled in the art. As described below, FIG. 3B and 3C (and FIG.
4 for views of the internal components) illustrate a typical dispensing
process for the dispenser 101.

[0069] If an axial impulse is suitably applied to the butt of the
activated plunger 109 shown in FIG. 3B, the plunger 109 further depresses
until it is fully depressed as depicted by FIG. 3C, after which the
plunger 109 reverts to its FIG. 3B position. During this complete
depression and reversion of the plunger 109, the idle crank 130 of FIG.
3B changes into the working crank 130 of FIG. 3C usually as follows: (1)
the crank housing 140 and associated crank guide 141 suitably advance
toward the reservoir body 127; (2) the crank guide 141 traverses crank
path 132 which axially torques the crank 130 relative to the reservoir
body 127 because grip 144 interacts with channel 143 to prevent the crank
housing 140 and associated crank guide 141 from axially rotating relative
to the reservoir body 127; (3) the crank housing 140 and associated crank
guide 141 suitably retreat away from the reservoir body 127; and, (4) the
crank guide 141 reverses crank path 132 which axially torques the crank
130 in the opposite direction relative to the reservoir body 127 because
grip 144 and channel 143 prevent the crank housing 140 and associated
crank guide 141 from axially rotating relative to the reservoir body 127.

[0070] At the immediate anterior of the reservoir body 127 is housed the
driver 129 and resistor 126 which are suitably held in longitudinal
position relative to the reservoir body 127 by the drive path 131 and
resistor path 145 respectively. The resistor 126 is fixed axially (may
not traverse resistor path 145), while the driver may rotate axially (may
traverse drive path 131). In other words, the driver 129, but not
resistor 126, may rotate axially relative to the reservoir body 127,
while both suitably do not move longitudinally from their position at the
anterior of the reservoir body 127. The driver 129 has driver teeth 133
on its lower side which interlock with the crank teeth 134 while the
crank guide 141 is traversing crank path 132 during activated plunger 109
depression. The driver teeth 133 and crank teeth 134 functionally
disengage while the crank guide 141 is reversing crank path 132 during
dispenser reversion from an open and dispensing configuration (FIG. 4C)
to an open configuration (FIG. 3B). A working crank 130 torques the
driver 129 relative to the reservoir body 127 and resistor 126 as the
crank guide 141 traverses crank path 132 because the crank teeth 134 and
driver teeth 133 are suitably interlocked, thereby inducing driver 129
rotation simultaneously and to the same degree as the crank 130. Though
the crank 130 rotates in the opposite direction as the crank guide 141
reverses crank path 132, the driver 129 does not, because usually the
crank teeth 134 and driver teeth 133 are functionally disengaged and
because of a resister 126. The resister 126 sits adjacent to the driver
129 in resistor path 145. The resistor 126 typically features resister
digits 137 that interact with digit grips 139 on the facing surface of
the driver 129 to allow the driver 129 to rotate simultaneously with the
crank 130 around driver path 131 as crank guide 131 traverses crank path
132, but to disallow driver 129 rotation in the opposite direction as
crank guide reverses crank path 132. Consequently, as dispenser 101
reverts to its open configuration, crank teeth 134 and driver teeth 133
may suitably slide past each other and reset for subsequent depression of
the plunger 109 and associated driver 129 rotation. Though the figures
depict driver teeth 133 and crank teeth 134 with profiles are cooperating
right triangles, those skilled in the art will know various other
mechanisms for accomplishing the same task. Though the resistor 126
features digits 137 which are bendable appendages which interact with
grips 139 having a profile of a right triangle, those skilled in the art
will know various other mechanisms for accomplishing the same task.

[0071] A rotating driver 129 is a working driver 129 because, as it
rotates, cooperating grooves 135 on the driver 129 and plunger shaft 121
interface and interact to coaxially screw the plunger shaft 121 into the
reservoir body 127. Because resister 126 only permits driver 129 rotation
in one direction, the plunger shaft 121 is not suitably unscrewed from
its position within the reservoir body 127. Each repeated depression of
the activated plunger 109 drives the plunger shaft 121 incrementally
further into the reservoir body 127. As a result, the idle piston 125 of
FIG. 3B changes into the working piston of FIG. 4C because the piston
moves incrementally further into the reservoir body 127. As the plunger
shaft 121 is incrementally driven into the reservoir body 127, it pushes
the piston 125 from the posterior of the chamber 128 toward the anterior
of the reservoir body 127, thereby decreasing the effective volume of the
chamber 128, and at the same time, moving the contained substance along
the applicator shaft 115 toward expulsion at the applicator tip 118.

[0072] As mentioned above, the dispenser 101 of the present invention
contemplates that the amount of contained substance induced to move by a
single plunger 109 depression may be set by the dispenser 101
manufacturer. The parameters of crank path 132 and the pitch of plunger
shaft 121 determine the degree of rotation achieved by the crank 130 and
therefore, the distance which plunger shaft 121 is screwed and the piston
125 is driven into the reservoir body 127. Knowing this distance, with
the geometric configuration of the chamber 128 and the thread pitch of
plunger shaft 121, allows the volume of substance expelled at the tip 118
during a single plunger 109 depression to be determined. Metered movement
of substance is important because the manufacturer can predict the life
of a dispenser 101 and adjust its retail stock accordingly (whether
dispenser 101 is disposable or refillable). Moreover, metered movement of
substance is important in that globbing, or over accumulation of
substance at the tip 118 can more easily be avoided by the user.

[0073] As mentioned above, the dispenser 101 of the present invention
suitably should not dispense substance through the applicator tip 118
while it is within the dispenser 101. As shown in the figures (FIG. 4 for
views of internal components), an axial initiating force applied to the
deactivated plunger 109 of FIG. 3A will not induce ejection of substance
from the applicator 117, even though a similarly applied impulse to
activated plunger 109 of FIG. 3B does. This apparent discrepancy is a
result of the plunger spring 123. For a dispenser 101 depicted by the
figures, the plunger spring 123 is suitably stiffer than retraction
spring 119. Therefore, when the two springs oppose each other, the
retraction spring 119 compresses sufficiently to achieve the
configuration of FIG. 3B before the plunger spring 123 compresses enough
to accomplish expulsion of substance through applicator 117. Once locked
into an open configuration of FIG. 3B, the plunger spring 123 opposes
depression of the plunger 109 along the plunger track 136 to the open and
dispensing position in FIG. 3C. Because there are normally no means for
locking the plunger spring 123 into a fully compressed state, the plunger
spring 123 usually expands after a plunger 109 depressing impulse, which
thereby causes reversion of the fully depressed plunger 109 of FIG. 3C to
the partially depressed plunger 109 of FIG. 3B. In an alternative
embodiment, arm 116 prevents the expulsion of substance while the
applicator tip 118 is concealed within dispenser 101. In this case, the
distal end of contracted arm 116 within the body 103, abuts the
internally housed edge of plunger 109, thereby preventing compression of
plunger spring 123 while the dispenser is in the deactivated state
illustrated by FIG. 1. By way of the plunger 109 interaction with arm
116, the plunger 109 depression drives the reservoir body to the anterior
of the body cavity 106, opens cap 105, and exposes the applicator tip 118
through anterior opening 102. Once the dispenser 101 attains an open
configuration illustrated by FIG. 3A, arm 116 extends away from the
internal edge of plunger 109 to interact with ledge 112 thereby locking
the dispenser in position. Since the arm 116 no longer interacts with
plunger 109, plunger spring 123 may be compressed by further plunger 109
depression and substance dispensed from the exposed applicator tip 118.

[0074] The dispenser 101 of the present application has a suitably
retractable applicator 117 (which usually features an applicator shaft
115 and applicator tip 118) which may electively be re-concealed after
use. Upon completion of desired dispensing, the lever 107 as an activated
reversion means may be selectively acted upon to invoke reversion to a
closed configuration. FIGS. 3A and 3B provide an illustration of this
type of reversion. The activated lever 107 of FIG. 3B is accessible at
slit 111. FIG. 3B shows the arm 116 extended to interact with ledge 112
just below orifice 111 to lock dispenser 101 in the open configuration.
When the lever 107 of FIG. 3B is deflected through slit 111, the lever
107 causes arm 116 to contract and dispenser 101 reverts to its FIG. 3A
configuration. After arm 116 contracts, the retraction spring 119
expands, the applicator 117 (which usually features an applicator shaft
115 and applicator tip 118) enters the body 103 through anterior opening
102, the shoot press moves toward the anterior of the body 103 which
draws the cap shoots 110 through the cap housing 122 into the body hollow
106, the cap 105 is suitably guided by flexor 113 to cap housing 122,
reservoir body 127 and arm 116 move from their anterior position to their
posterior positions, the plunger 109 and its internal components extend
fully from the dispenser body 103, and finally the cap 105 seals anterior
opening 102.

[0075] FIG. 4 is an exploded view of the dispenser 101 depicted in the
figures. FIG. 4 is also an inventory of parts, and a construction diagram
for the dispenser 101 of FIGS. 1, 2A, 2B, 3A, 3B and 3C. The components
generally fit together by following the dashed line from the top left to
the bottom right of the FIG. 4. More specifically, after substance has
been loaded into the chamber 128, the piston 125 couples with plunger
shaft 121 (AA to AA') and together the piston 125 and plunger shaft 121
merge approximately coaxially with the reservoir body 127 through its
anterior, such that the piston 125 defines an anterior, inner wall of
chamber 128 and plunger shaft 121 is extended out of the reservoir body
127 rear. The exposed end of the plunger shaft 121 suitably inserts
coaxially into the resister 126 (BB to BB'), and coaxially into the
driver 129 (CC to CC') by way of cooperating grooves 135 at the plunger
shaft 121 and driver 129 interface. The resister 126 and driver are
suitably positioned at the reservoir body anterior in the resistor path
145 and driver path 131 respectively. The driver 129 is positioned so
that its posterior portion inserts coaxially into the female, anterior
end of the crank 130 (DD to DD'), and so the driver teeth 133 are subject
to interaction with crank teeth 134 (EE to EE'). Any portion of the
plunger shaft 121 which remains exposed from the driver 129 will also
suitably be inserted into the crank 130 with the driver 129 posterior.
The crank 130 posterior is operationally configured for insert into
plunger spring 123 without obstructing the crank path 132. In the present
embodiment, a male member 146 having a reduced diameter relative to the
main portion of the crank 130, protrudes from the crank 130 posterior
which member 146 may then be inserted into anterior of the plunger spring
123 (FF to FF'). The difference in diameter between the member 146 and
the main portion of the crank 130 prevents the plunger spring 123 from
obstructing the crank path 132. The posterior of the plunger spring 123
is thereafter inserted into the crank housing 140 cavity (GG to GG')
wherein crank guide 141 is positioned for unobstructedly
traversing/reversing crank path 132 (HH to HH') as discussed above.
Thereafter all the aforementioned components beginning with the reservoir
body 127 and ending with the crank housing 140 are positioned within the
plunger cavity 108 so that the grip 144 and channel 143 align with the
appropriate cooperating locations within the plunger cavity 108, and so
the reservoir body 127 interacts with the plunger 109 at plunger track
136 (II to II'). The arm 116 may then be attached to the anterior of the
reservoir body 127 (JJ to JJ'). The applicator shaft 115 is usually
coaxially inserted through the shoot press 124 so that the shoot press
124 is adjacent to the reservoir body 127 anterior (KK to KK'). The
retraction spring 119 may then be placed around the applicator shaft 115
(LL to LL') but into the shoot press 124 (MM to MM'). The posterior of
spring stop 120 inserts masculinely into spring 119 (NN to NN') but
femininely receives the applicator shaft 115 (OO to OO') and usually
abuts the shoot press 124. The applicator tip 118 may then be positioned
at the distal end of applicator shaft 115 (PP to PP'). The applicator tip
118 may then be positioned/inserted at the anterior portion of cap
housing 122 (QQ to QQ'). The cap shoots 110 are fastened to shoot press
124 (RR to RR') and passed through the spring stop 120 at notch 147 and
the cap housing 122 (SS to SS'), after which they are fastened to cap 105
as shown in FIG. 4. The cap 105 may then be situated at the cap housing
122 (TT to TT'). Finally, all afore mentioned components, beginning with
the plunger 109 and ending with the cap housing 122, are inserted into
the anterior opening of the dispenser body 103 until the plunger 109 is
prevented from further extending out from the anterior opening 104 (UU to
UU') by the nub 138, and the cap housing 122 is forced into the body 103
anterior (VV to VV').

[0076] After contained substance stock is sufficiently diminished by
dispenser 101 use, the dispenser 101 may be disposed of or replenished
with substance. If replenishment of substance is desired, usually the
internal components are reset accordingly and the chamber re-stocked with
substance. This application contemplates that a dispenser 101, and
reservoir, may be either disposable or refillable.

[0077] The figures depict the dispenser 101 with a rigid but hollow
tubular body 103, a rigid but hollow cylindrical plunger 109, and other
components of various shapes and relative sizes. However, the body 103
and plunger 103 need not be tubular or cylindrical but may be any shape
seen fit by a person skilled in the applicable art. In addition to
cylinders, other shapes, including, but not limited to squared, polygonal
shapes, may be employed. Similarly, the various components shape and
relative size may also be so modified. For example, a dispenser 101
depicted by the figures may have the general appearance of a right
cylinder, but the general appearance may also be that of any
three-dimensional object.

[0078] The materials suitable for forming the dispenser 101 and its
components will vary depending on the physical properties of the
substance contained, and the nature of the expected dispenser 101 use.
The proper combination of materials for contained substance will be
readily apparent to those skilled in the art. Keeping that in mind, the
components of a dispenser 101 may be formed using a variety of preferable
materials, including but not limited to metals, alloys, composites,
woods, and a variety of hard plastics including but not limited to
high-density polyethylene, polypropylenes, PVC, and other materials that
will be appreciated by those skilled in the art.

[0079] An alternate embodiment of the present application is the dispenser
201. Dispenser 201 is functionally similar to the previous embodiment 101
contemplated by FIGS. 1-6, with variations as set forth below. More
specifically, aspects and components for dispenser 201 are similar to the
corresponding ones of the earlier described preferred embodiment 101.

[0080] FIG. 7 depicts a dispenser 201 in a closed configuration. Similar
to FIG. 1, FIG. 7 shows a dispenser 201 featuring a body 203 and a slit
211 coupled to a cap housing 222 with a lever 207 at the body 203
anterior, which lever 207 suitably defines an excrescence on the
dispenser 201. FIG. 7 also shows the anterior of the dispenser 201
suitably occupied by a cap 205 and cap housing 222 preferably for
variably sealing the anterior opening 202 of the dispenser 201. The
posterior of the body 203 is suitably occupied by a plunger 209 that
typically coaxially merges into (or with) the body 203 by way of the
posterior opening 204. Similar to the corresponding components of the
dispenser 101 of FIG. 1, in FIG. 7, the plunger 209 represents a
deactivated trigger and the anterior opening 202 represents an exit
location for the applicator 217. As detailed below, the lever 207 is an
inactive reversion means, meaning that it may function to release the
applicator 217 from a fixed extended position, allowing it to be
selectively retracted by the user into the dispenser 201. Also detailed
below, in FIG. 7 the cap housing 222, body 203, and plunger 209 have
various internally concealed components.

[0081] FIG. 8A typifies a dispenser 201 in an open configuration. The
figure illustrates a cap 205 held open and away from anterior opening 202
by a pair of rigid, yet flexible, cap shoots 210 and a stem 213. Similar
to FIG. 2A, FIG. 8A also depicts the protrusion of an applicator 217
through the exposed anterior opening 202. An activated lever 207 is
accessible at slit 211, and a partially depressed plunger 209 extends
from the posterior opening 204. In FIG. 8A the anterior opening 202 is
the exit location for applicator 217. As detailed further below, the
lever 207 is suitably an activated reversion means. Also detailed below,
in FIG. 8A the cap housing 222, body 203 and plunger 209 have various
internal components.

[0082] The dispenser 201 of the present application has a suitably
retractable applicator 217 which may be electively exposed for applicator
tip 218 use. Similar to the earlier preferred embodiment 2, elective
transition from a closed to an open configuration is usually achieved
through application of an initiating force which suitably activates the
plunger 209 as a trigger, exposes anterior opening 202, and protrudes the
applicator 217 from the dispenser 201. In most instances, the acting
force on the plunger 209 will be generated by the user manually, for
instance by a thumb or finger. The dispenser 201 typically has a natural
tendency to revert from an open to a closed configuration. As discussed
further herein, during transition from closed to open configurations,
this tendency is normally continuously opposed to applicator 217
protrusion and plunger 209 activation. However, once the plunger 209 has
been activated, the applicator 217 is suitably locked in external
position and natural reversion to a closed configuration is prevented.
Also discussed further herein, once the dispenser 201 is suitably locked
into an open configuration, the lever 207 suitably becomes an activated
reversion means which may electively be acted upon to release the lock,
thereby enabling the aforementioned natural tendency to actuate reversion
to a closed configuration. FIGS. 7 and 8A taken together may help
visualize this transition. Referring to these two figures, when an
external axial force is applied to the butt of the plunger 209 in FIG. 7,
such force depresses the plunger 209, extrudes cap shoots 210 from cap
housing 222, releases the cap 205 along flexor 213, and projects
applicator 217 from the anterior opening 202. Once the force moves the
plunger 209 to its partially depressed position in

[0083] FIG. 8A, plunger 209 and lever 207 are activated and the
configuration is usually locked in place. At this point, reversion to the
closed state of FIG. 7 normally can only be attained through interaction
with lever 207. See the discussion below for more details.

[0084] FIG. 8B depicts a dispenser 201 in an open and dispensing
configuration. The FIG. 8B configuration is suitably necessary for
expulsion of contained substance through an exposed applicator tip 218.
As seen in the figure, a dispenser 201 in such an open and dispensing
configuration has components in roughly the same relative positions as
that of FIG. 8A, but the plunger 209 is suitably depressed fully toward
the body 203. In other words, the depressed and active plunger 209 may be
typically used as an active trigger to forcibly eject cosmetic substance
from an applicator tip 218 of the dispenser 201.

[0085] Transition from an open (FIG. 8A) to an open and dispensing (FIG.
8B) configuration is usually accompanied by a motive force placed upon
the contained substance. The motive force may preferably be caused by the
plunger 209 being fully depressed and active. A fully depressed and
active plunger 209 typically results from axial impulse on the end of the
activated plunger 209, as shown in FIG. 8A. As discussed in more detail
below, this impulse preferably induces metered dispensing of a contained
substance from the exposed applicator tip 218. Applicator 217 may feature
at least one, or a plurality of orifices through which substance may be
expelled. Dissipation of the aforementioned impulse results in reversion
of the plunger 209 from fully to partially depressed and suitably ends
dispensing of substance until a new impulse is triggered. Usually there
is no mechanism to lock the dispenser in an open and dispensing
configuration. FIGS. 8A and 8B together may help visualize this process.
Referring to these two figures, when an external axial impulse is applied
to the butt of the plunger 209 of the dispenser 201 in FIG. 8A, this
impulse usually fully depresses the plunger 209 to its position in FIG.
8B which induces metered expulsion of a contained substance from
applicator tip 218. Upon dissipation of the axial impulse, the fully
depressed plunger 209 preferably automatically returns to its position in
FIG. 8A. A typical use cycle would entail impulsive depression of the
plunger 209 from its partially depressed position in FIG. 8A to a fully
depressed position of FIG. 8B, followed by reversion to its partially
depressed position in FIG. 8A. Normally, the cosmetic dispensing feature
of dispenser 201 is accomplished by the plunger 209 being cycled
repeatedly to cause sufficient accumulation of contained substance at the
applicator tip 218, where a user would then apply the substance to the
lips, eyes, face, or the like.

[0086] Still referring to FIGS. 8A and 8B, the specifics of the applicator
217 (usually including the applicator shaft 215 and applicator tip 218)
depend on the type of substance and the nature of the dispenser 201
purpose. In the accompanying figures, the applicator tip 218 is a hollow
truncated cylinder with an angled cylindrical section as the applicator
tip 218 surface, as one might see in a lip gloss applicator. In some
instances, however, the applicator tip 218 may just be an orifice or
other type of opening through which a substance may be discharged. In
another instance, the applicator tip 218 may be a membrane through which
substance may be expelled. In yet another instance, the applicator tip
218 may be some type of rigid member to which expelled substances may
adhere while awaiting application (e.g., a brush disposed over an orifice
whereby the brush bristles collect substance expelled thereon).

[0087] FIGS. 8C, 8D, and 8E are side views of the dispenser 201 which
respectively correspond to the closed, open, and open and dispensing
configurations of FIGS. 7, 8A and 8B.

[0088] FIG. 9 is a longitudinal cross-section of the dispenser 201 of
FIGS. 7 and 8C (since the figure is a cross-section, the specific
features of the depicted components are best viewed by reference to FIG.
10 which is an exploded view of the dispenser). The figure shows a
dispenser 201 with a closed cap 205 and body hollow 206 which houses the
applicator 217 including the applicator shaft 215 and applicator tip 218,
the retraction spring 219, the cap shoots 210, the shoot press 224, edge
212, a movable reservoir body 227 (which contains the piston 225, and
part of the plunger shaft 221), resistor 226, drive gear 229, and crank
230. The figure also shows a dispenser with a plunger cavity 208 that
houses the plunger spring 223, the crank housing 240, and most of the
plunger shaft 221, drive gear 229 and crank 230. In FIG. 9 the plunger
209 is fully extended away from the body 203 and the internal components
of the body hollow 206 are toward the body 203 posterior. The reservoir
body 227 and its chamber 228 are an enclosure configured to contain
cosmetic substances, which are usually fluid or powder in nature. Typical
substances include, but are not limited to, lipstick, mascara, lip gloss,
blemish remover, concealers, eyeliners, and the like as will be
appreciated by those skilled in the industry. The applicator shaft 215
suitably defines an avenue or channel between the applicator tip 218 and
the chamber 228 containing substance. In other words, the applicator
shaft 215 and chamber 228 are suitably in fluid connection with one
another.

[0089] When the dispenser 201 is an open configuration as depicted in FIG.
8A, the cap 205 may suitably be held open and away from anterior opening
202 by a pair of rigid, yet flexible, cap shoots 210 and a stem 213
pivotably mounted to the cap housing 222. Further, the applicator 217
(which usually includes applicator tip 218 and applicator shaft 215) may
preferably protrude through the exposed anterior opening 202 while the
dispenser 201 is open. Referring to FIG. 9 in view of FIG. 10 and the
corresponding components of the dispenser 201 in FIG. 3A, the body hollow
206 of an open dispenser 201 houses the following components: the
retraction spring 219 which may be compressed against the spring stop
220; the shoot press 224 which may push, as the reservoir 227 shifts to
the anterior of the dispenser 201 the cap shoots 210 through the cap
housing 222; the slot 216 extended to the edge 212; and the reservoir
body 227, which is locked in its position and which contains the piston
225 and part of the plunger shaft 221, resistor 226, drive gear 229, and
crank 230. Still referring to FIG. 9 in view of FIGS. 3B and 10, an open
dispenser 201 features a plunger cavity 208 that houses the plunger
spring 223, idle plunger shaft 221, resistor 226, drive gear 229, and
crank 230. In the open configuration, the plunger 209 is suitably
activated and more depressed within the body 203 than the deactivated
plunger 209 of FIG. 9 whereby the internal components of the body 203
hollow 206 are more toward the dispenser 201 anterior in the same general
manner as depicted in FIG. 3B.

[0090] When the dispenser 201 is in the open and dispensing configuration
of FIG. 8B, the dispenser 201 components are similarly situated to the
open configuration of FIG. 8A except that plunger 209 may be fully
depressed to within the dispenser 201. Referring now to FIG. 9 in view of
FIG. 3C and 10, the open and dispensing dispenser 201 preferably features
a plunger cavity 208 which suitably houses a compressed plunger spring
223, a working plunger shaft 221, resistor 226, piston 225, drive gear
229 and crank 230.

[0091] As mentioned above, a dispenser 201 transition from a closed to
open configuration is opposed by a natural tendency to remain in and
revert to a closed configuration. FIGS. 7, 8A and 9 (and FIG. 10 for
views of internal components) provide an illustration of such a natural
tendency. These figures show a dispenser 201 with a retraction spring
219. FIGS. 1 and 9 depict the retraction spring 219 while the dispenser
201 is in a closed configuration. Transitioning from the dispenser 201 of
FIGS. 7 and 9 to that shown in FIG. 8A is accomplished by depressing the
plunger 209 to within the dispenser 201 in similar manner disclosed above
with respect to FIGS. 3A and 3B whereby the retraction spring 219 may
compress against the spring stop 220 and reservoir body 227 while the cap
press 224 suitably pushes the cap 205 open via the cap presses 210. More
specifically, plunger 209 depression suitably may accomplish at least the
following: (1) moves the reservoir body 227, shoot press 224, and slot
216 toward the anterior; (2) extrudes the cap shoots 210 through cap
housing 222 to pivotably open the cap 205 around the stem 213; (3) drives
the applicator 217 protrusion; and, (4) suitably compresses the spring
219 between the spring stop 220 and the moving reservoir body 227. Thus,
the force of compressed retraction spring 219 may be constantly opposed
to plunger 209 depression, applicator 217 protrusion, and an open
dispenser 201 configuration. The transition from a closed dispenser 201
of FIGS. 7 and 9 to an open dispenser 201 of FIG. 8A is accomplished when
the slot 216 interfaces with the edge 212 whereby the dispenser 201 is
locked open. In the open configuration, the plunger 209 is suitably
activated.

[0092] Though the figures depict retraction spring 219 as the natural
tendency, an internal compression spring is not the only means for
inducing the aforementioned natural tendency. Such natural tendency may
be invoked internally or externally through the use of magnets, elastics,
rubbers, manual or any other attractive or repulsive force.

[0093] As mentioned above, until dispenser 201 is locked into the open
configuration, the natural tendency will suitably invoke reversion to a
closed configuration. Similar to the earlier disclosed embodiment 101,
the dispenser 201 of the present application typically uses a suitable
latching means to lock the open configuration when the applicator 217 has
been protruded sufficiently from the anterior opening 202. The latching
means may remove the natural tendency or suitably counteract its force.
Similar to FIG. 3A and 3B (in view of FIG. 4), FIG. 9 (in view of FIG.
10) illustrates a latching means. FIG. 9 depicts a slot 216 set into the
reservoir body 227 for interfacing with an edge 212 notched within the
body 203 preferably below the lever 207 (note: the nub next to the slot
216 is a fulcrum point for the lever 207). Application of an axial
initiating force at the plunger 109 butt, depresses the deactivated
plunger 209 of FIG. 9, and moves the slot 216 toward edge 212 below lever
207 and slit 211. Similar to the earlier embodiment, the nub interfaces
with the edge 212 such that compressed retraction spring 219 cannot
expand to force the dispenser 201 to a closed configuration.

[0094] Though the figures depict a slot 216 and edge 212 as the latching
mechanism for dispenser 201, there are many other suitable latching
means. This latching means might take the form of a hook, lever,
constriction, latch, adhesive, friction, and by other means that would be
appreciated by those skilled in the art.

[0095] As alluded to above, the plunger 209 becomes an activated trigger
in the open configuration since further depression accomplishes expulsion
of contained substance from the exposed applicator 217 at the applicator
tip 218. To prevent undesired and unintentional internal ejection of
contained substance at the applicator tip 218, the plunger 209 is not
used to eject substance until dispenser 201 is in the open configuration.
As mentioned above, the deactivated plunger 209 of FIG. 9 may be
depressed by an initiating force until slot 216 meets edge 212 to lock
the dispenser in its FIG. 8A configuration. Beginning at FIG. 9, an
initiating force applied to the butt of deactivated plunger 209 moves at
least one of the reservoir body 227, shoot press 224, and slot 216 from a
posterior position to an anterior position within the dispenser. During
depression, the retraction spring 219 suitably compresses against spring
stop 220 and reservoir body 227, the cap shoots 210 preferably extrude
out of the cap housing 222, the cap shoots 210 force open the cap 205
while the stem 213 pivotably guides the cap 205 away from anterior
opening 202, and the applicator 217 (which usually includes applicator
shaft 215 and applicator tip 218) protrudes from the dispenser 201
through the anterior opening 202 (see FIG. 8A). When locked in this open
configuration, the plunger 209 is activated because further plunger 209
depression induces substance movement along applicator shaft 215
culminating with ejection through the applicator 217, suitably by way of
the applicator tip 218.

[0096] A lever 207 becomes an activated reversion switch when action upon
it results in reversion from an open to closed configuration. A lever 207
as a reversion switch is a suitable means for unlocking the open
configuration. FIG. 8A and 9 (and FIG. 10 for views of the internal
components) illustrate the activation of a lever 207 as a reversion
switch. In FIG. 8A, slot 216 interacts with ledge 212 below the slit 211
to prevent retraction spring 219 from expanding from its compressed
state. While slot 216 is interacting with edge 212, lever 207 deflection
is required to dissociate the slot 216 from the edge 212 and thereby
effectuate reversion of dispenser 201 to a closed configuration. In the
open configuration, the lever 207 of FIG. 8B is an activated reversion
switch because acting thereon shifts the edge 212 away from the slot 216,
and allows retraction spring 219 to push the exposed applicator 217
(which usually features an applicator shaft 215 and an applicator tip
218) back within the body to the FIG. 9 configuration. The lever 207 in
FIG. 9 is inactive because acting on it does not result in reversion.
Finally, as mentioned above, lever 207 suitably defines an excrescence on
the dispenser 201 in order that lever 207 may be more readily identified
whether by sight or feel. However, the degree or extent of desirable
excrescence will vary and change depending on desired dispenser 201 use
and in some instances a lever 207 may be flush with the dispenser 201
surface and not define an excrescence at all. Such details will be
apparent to those skilled in the art. Though the figures depict the lever
207 in association with slit 211 as a reversion switch, anything that
releases the dispenser 201 latching means may be used as a reversion
switch.

[0097] Another feature of the dispenser 201 is the cap 205 which, in
conjunction with an elastomeric spring stop 220 and the applicator shaft
215, electively seals or unseals the anterior opening 202, typically by
way of a substantially air or water tight pocket. FIGS. 7, 8A, 8B and 9
(and FIG. 10 for views of the internal components) provide an
illustration of the cap 205 in operation. While dispenser 201 is in a
closed configuration like that of FIGS. 7 and 9, the cap 205 suitably
seals the anterior opening 202 of the dispenser 201 as follows: the
retraction spring 219 may be fully extended and thereby preferably forces
against the reservoir body 227 to press the spring stop against the cap
housing 222; the shoot press 224 suitably pulls the cap shoots 210 taut,
which tension usually interlocks the cap 205 with the cap housing 222 and
secures the cap 205 over the anterior opening against the anterior of
spring stop 220; the tension on the cap shoots 210 between the shoot
press 224 and the cap 205 suitably squeezes the spring stop 220 between
the cap 205 and the cap housing 222 thereby forcing deformation of the
elastomeric spring stop 220 until the anterior opening 202 is
substantially air or water tight; and finally, at the posterior of the
spring stop 220, the applicator shaft 215, which is coaxial to the spring
stop 220 and which has an increasing diameter toward the applicator 217,
forces deformation of the posterior of the spring stop 220 by way of its
increasing diameter relative to the diameter of the spring stop 220 (see
FIG. 8A). Accordingly, a substantially air or water tight pocket is
created between the cap 205, the spring stop 220 and the applicator shaft
215. Further, the dispenser 201, under such a seal, can withstand
internal pressures associated with the containment of volatile fluids.
Other sealing means preferably may be placed throughout the dispenser 201
to effectuate an optional air or water tight dispenser 201. As
illustrated by 8A and 9, to unseal the cap 205, plunger depression moves
the reservoir body 227 and shoot press 224 internally toward the anterior
opening 202, the shoot press 224 preferably forces the cap shoots 210
through the cap housing 222, and the cap 205 is forced off of the
anterior opening 202 by the cap shoots 210 and drawn away by the pivoting
stem 213.

[0098] Also, as the tip 218 is exposed from anterior opening 202, the
decreasing diameter of the applicator shaft 215 relative to the posterior
of the spring stop 220 permits the elastomeric spring stop 220 to return
to equilibrium. A substantially air or water tight pocket at the anterior
opening is useful to prevent contamination, corruption, or
dehydration/drying of the tip 218 and contained substance. Additionally,
attached to the distal end of the stem 213 is a pivoting mechanism which
interacts with cap housing 222 to extend the useful life the seal. This
feature typically allows the cap 205 to come down evenly on the seal
surface of spring stop 220 without applying to much pressure to one side
of the elastomeric spring stop 220 and possibly deforming it over time.

[0099] The dispenser 201 of the present application normally ejects a
substance through the exposed applicator 217 at the applicator tip 218
after an impulse has sufficiently depressed a plunger 209 and induced
movement of a contained substance along an applicator shaft 215 between
the applicator tip 218 and the chamber 228. Movement of said contained
substance along the applicator shaft 215 may be realized by a piston,
pump, suction, expansion, compression or otherwise as will be appreciated
by those skilled in the art. As described below, FIG. 8A, 8B and 9 (and
FIG. 10 for views of the internal components) illustrate a typical
dispensing process for the dispenser 201.

[0100] In response to an axial impulse that is suitably applied to the
butt of the activated plunger 209 shown in FIG. 8A, the plunger 209
further depresses until it is fully depressed as depicted by FIG. 8B,
after which the plunger 209 reverts to its FIG. 8A position. During this
complete depression and reversion of the plunger 209, the crank 230 as
seen in FIGS. 9 and 10 changes into a working crank 230 as follows: (1)
the crank housing 240 and associated crank guide 241 suitably advance
toward the reservoir body 227; (2) the crank guide 241 (as seen in FIG.
10) traverses crank path 232 which axially torques the crank 230 relative
to the reservoir body 227 because grip 244 interacts with channel 243 to
prevent the crank housing 240 and associated crank guide 241 from axially
rotating relative to the reservoir body 227; (3) the crank housing 240
and associated crank guide 241 suitably retreat away from the reservoir
body 227; and, (4) the crank guide 241 reverses crank path 232 which
axially torques the crank 230 in the opposite direction relative to the
reservoir body 227 because grip 244 and channel 243 prevent the crank
housing 240 and associated crank guide 241 from axially rotating relative
to the reservoir body 227.

[0101] At the immediate anterior of the reservoir body 227 is housed the
driver 229 and resistor 226 which are suitably held in longitudinal
position relative to the reservoir body 227 by the drive path 231 and
resistor path 245 respectively. The resistor 126 is fixed axially (may
not traverse resistor path 245), while the driver may rotate axially (may
traverse drive path 231). In other words, the driver 229, but not
resistor 226, may rotate axially relative to the reservoir body 227,
while both suitably do not move longitudinally from their position at the
anterior of the reservoir body 227. The driver 229 has driver teeth 233
on its lower side which interlock with the crank teeth 234 while the
crank guide 241 is traversing crank path 232 during activated plunger 209
depression. The driver teeth 233 and crank teeth 234 functionally
disengage while the crank guide 241 is reversing crank path 232 during
dispenser reversion from an open and dispensing configuration (FIG. 8B)
to an open configuration (FIG. 8A). A working crank 230 torques the
driver 229 relative to the reservoir body 227 and resistor 226 as the
crank guide 241 traverses crank path 232 because the crank teeth 234 and
driver teeth 233 are suitably interlocked, thereby inducing driver 229
rotation simultaneously and to the same degree as the crank 230. Though
the crank 230 rotates in the opposite direction as the crank guide 241
reverses crank path 232, the driver 229 does not, because usually the
crank teeth 234 and driver teeth 233 are functionally disengaged and
because of a resister 226. The resister 226 sits adjacent to the driver
129 in resistor path 245. The resistor 226 typically features resister
digits 237 that interact with digit grips 239 on the facing surface of
the driver 229 to allow the driver 229 to rotate simultaneously with the
crank 230 around driver path 231 as crank guide 231 traverses crank path
232, but to disallow driver 229 rotation in the opposite direction as
crank guide reverses crank path 232. Consequently, as dispenser 201
reverts to its open configuration, crank teeth 234 and driver teeth 233
may suitably slide past each other and reset for subsequent depression of
the plunger 209 and associated driver 229 rotation. Though the figures
depict driver teeth 233 and crank teeth 234 whose profiles are
cooperating triangles, those skilled in the art will know various other
mechanisms for accomplishing the same task. Though the resistor 226
features digits 237 which are bendable appendages which interact with
grips 239 having a profile of a triangle, those skilled in the art will
know various other mechanisms for accomplishing the same task.

[0102] A rotating driver 229 is a working driver 229 because as it
rotates, cooperating grooves 235 on the driver 229 and plunger shaft 221
interface, interact to coaxially screw the plunger shaft 221 into the
reservoir body 227. Because resister 226 only permits driver 229 rotation
in one direction, the plunger shaft 221 is not suitably unscrewed from
its position within the reservoir body 227. Each repeated depression of
the activated plunger 209 drives the plunger shaft 221 incrementally
further into the reservoir body 227. As a result, the piston 225 moves
incrementally further into the reservoir body 127. As the plunger shaft
221 is incrementally driven into the reservoir body 227, it suitably
pushes the piston 225 from the posterior of the chamber 228 toward the
anterior of the reservoir body 227, thereby decreasing the effective
volume of the chamber 228, and at the same time, moving the contained
substance along the applicator shaft 215 toward expulsion at the
applicator tip 218.

[0103] As mentioned above, the dispenser 201 of the present invention
contemplates that the amount of contained substance induced to move by a
single plunger 209 depression may be set by the dispenser 201
manufacturer. The parameters of crank path 232 and the thread pitch of
plunger shaft 221 determine the degree of rotation achieved by the crank
230 and therefore, the distance which plunger shaft 221 is screwed and
the piston 225 is driven into the reservoir body 227. Knowing this
distance, with the geometric configuration of the chamber 228 and the
thread pitch of plunger shaft 221, allows the volume of substance
expelled at the tip 218 during a single plunger 209 depression to be
determined. Metered movement of substance is important because the
manufacturer can predict the life of a dispenser 201 and adjust its
retail stock accordingly (whether dispenser 201 is disposable or
refillable). Moreover, metered movement of substance is important in that
globbing, or over accumulation of substance at the tip 218 can more
easily be avoided by the user.

[0104] As mentioned above, the dispenser 201 of the present invention
suitably should not dispense substance through the applicator tip 218
while it is within the dispenser 201. As shown in the figures, an axial
initiating force applied to the deactivated plunger 209 of FIG. 9 will
not induce ejection of substance from the applicator 217, even though a
similarly applied impulse to activated plunger 209 of FIG. 8A does. This
apparent discrepancy is a result of the plunger spring 223. For a
dispenser 201 depicted by the figures, the plunger spring 223 is suitably
stiffer than retraction spring 219. Therefore, when the two springs
oppose each other, the retraction spring 219 compresses sufficiently to
achieve the configuration of FIG. 8A before the plunger spring 223
compresses enough to accomplish expulsion of substance through applicator
217. Once locked into an open configuration of FIG. 8A, the plunger
spring 223 opposes depression of the plunger 209 along the plunger track
236 to the open and dispensing position in FIG. 8B. Because there are
normally no means for locking the plunger spring 223 into a fully
compressed state, the plunger spring 223 usually expands after a plunger
209 depressing impulse, which thereby causes reversion of the fully
depressed plunger 209 of FIG. 8B to the partially depressed plunger 209
of FIG. 8A.

[0105] The dispenser 401 of the present application has a suitably
retractable applicator 217 (which usually features an applicator shaft
215 and applicator tip 218) which may electively be re-concealed after
use. Upon completion of desired dispensing, the lever 207 as an activated
reversion means may be selectively acted upon to invoke reversion to a
closed configuration. FIGS. 7, 8A, 9, and 10 provide an illustration of
this type of reversion. The activated lever 207 of FIG. 8A is accessible
at slit 211 (best depicted in FIG. 10). As discussed above, the slot 216
is adapted to extended for interaction with edge 212 just below the lever
207 to lock the dispenser 201 in the open configuration. When the lever
207 of FIG. 8A is deflected through slit 211, the lever 207 causes the
edge 212 to disassociate from the slot 216 whereby the dispenser 201
reverts to its

[0106] FIGS. 7 and 9 configuration. After slot 216 and edge 212
disassociation, the retraction spring 219 expands, the applicator 217
(which usually features an applicator shaft 215 and applicator tip 218)
enters the body 203 through anterior opening 202, the shoot press moves
toward the anterior of the body 203 which draws the cap shoots 210
through the cap housing 222 into the body hollow 206, the cap 205 is
suitably guided by flexor 213 to cap housing 222, reservoir body 227 and
slot 216 move from their anterior position to their posterior positions,
the plunger 209 and its internal components extend fully from the
dispenser body 203, and finally the cap 205 seals anterior opening 202.

[0107] FIG. 10 is an exploded view of the dispenser 201 depicted in the
figures. FIG. 10 is also an inventory of parts, and a construction
diagram for the dispenser 201. The components generally fit together by
following the dashed line from the top left to the bottom right of the
FIG. 10. More specifically, the dispenser may be assembled according to
the following method: (1) the spring 223 may be placed into the crank
housing (A to A'); (2) the crank 230 may be inserted into the crank
housing 240 (B to B') whereby the spring 223 and crank 240 (C to C')
interface while the crank guide 241 occupies the crank path 232 (D to D')
and is preferably positioned for unobstructedly traversing/reversing
crank path 232 as discussed above; (3) the piston 225 couples with
plunger shaft 221 (E to E') and together the piston 225 and plunger shaft
221 merge approximately coaxially with the reservoir body 227 through its
anterior, such that the piston 225 defines an anterior, inner wall of
chamber 228 and plunger shaft 221 is extended out of the reservoir body
227 rear; (4) the exposed end of the plunger shaft 221 suitably inserts
coaxially into the resister 226 (F to F'), and coaxially into the driver
229 (F to F'') by way of cooperating grooves 235 at the plunger shaft 221
and driver 229 interface; (5) The resister 226 and driver are suitably
positioned at the reservoir body 227 anterior in the resistor path 245
and driver path 231 respectively (H to H'; I to I'); (6) the crank
housing 240 may be coaxially inserted into the plunger 209 (J to J'); (7)
the reservoir body 227 is coaxially inserted into the plunger 209 (K to
K') whereby the driver 229 is positioned so that its posterior portion
inserts coaxially into the female, anterior end of the crank 230 (L to
L') (it should be noted that any portion of the plunger shaft 221 which
remains exposed from the driver 229 and reservoir body 227 will also
suitably be inserted into the crank 230 with the driver 229 posterior),
whereby the driver teeth 233 are subject to interaction with crank teeth
234 (M to M'), and whereby the grip 244 interacts with channel 243 (N to
N'); (8) the cap 205, cap shoot 210, and cap press 224 component may be
installed on the cap housing 222 (O to O') whereby the stem 213 is
pivotably attached thereto (P to P'); (9) the spring stop 220 may be
inserted into the cap housing 222 (Q to Q'); (10) the spring 219 may be
provided to the cap housing 222 (R to R') whereby the spring stop 220 and
spring 219 interface (S to S') therein; (11) the reservoir body 227, and
component assembled thereto, may be inserted into the body 203 (T to T');
(12) the body 203, and components assembled thereto, may be inserted into
the cap housing 222 (U to U') whereby the lever 207 extends from the cap
housing 222 (V to V'), the reservoir body 227 inserts into and receives
the spring 219 (W to W'); and the cap press 224 couples to the reservoir
body 227 (X to X'); and, (13) the dispenser 201 may be opened as
discussed above, contents deposited into the reservoir body 227, and the
applicator 217 may be coupled to applicator shaft 215 (Y to Y') through
the exposed anterior opening 202 of the dispenser 201.

[0108] After contained substance stock is sufficiently diminished by
dispenser 201 use, the dispenser 201 may be disposed of or replenished
with substance. If replenishment of substance is desired, usually the
internal components are reset accordingly and the chamber re-stocked with
substance. This application contemplates that a dispenser 101, and
reservoir, may be either disposable or refillable.

[0109] The figures depict the dispenser 201 with a rigid but hollow
tubular body 203, a rigid but hollow cylindrical plunger 209, and other
components of various shapes and relative sizes. However, the body 203
and plunger 203 need not be tubular or cylindrical but may be any shape
seen fit by a person skilled in the applicable art. In addition to
cylinders, other shapes, including, but not limited to squared, polygonal
shapes, may be employed. Similarly, the various components shape and
relative size may also be so modified. For example, a dispenser 201
depicted by the figures may have the general appearance of a right
cylinder, but the general appearance may also be that of any
three-dimensional object.

[0110] The materials suitable for forming the dispenser 201 and its
components will vary depending on the physical properties of the
substance contained, and the nature of the expected dispenser 201 use.
The proper combination of materials for contained substance will be
readily apparent to those skilled in the art. Keeping that in mind, the
components of a dispenser 201 may be formed using a variety of preferable
materials, including but not limited to metals, alloys, composites,
woods, and a variety of hard plastics including but not limited to
high-density polyethylene, polypropylenes, PVC, and other materials that
will be appreciated by those skilled in the art. It is further preferable
that the body 203 and the reservoir body 227 be transparent whereby the
properties (e.g., color) of the deposited substance may be apparent to a
user without opening the dispenser 201.

[0111] An alternate embodiment of the present application is the dispenser
301. Dispenser 301 is functionally similar to the previous embodiment 301
contemplated by FIGS. 1-10, with variations as set forth below. More
specifically, aspects and components for dispenser 301 are similar to the
corresponding ones of the earlier described preferred embodiment 101.

[0112] FIG. 11A depicts a dispenser 301 in a closed configuration. FIG.
11B depicts a dispenser 301 in an open configuration. FIGS. 12A, 12B,
13A, and 13B respectively depict a side view of the dispenser 301 of FIG.
11A, a side view of the dispenser 301 of FIG. 11B, a top view of the
dispenser 301 of FIG. 11A, and a top view of the dispenser 301 of FIG.
11B. The figures illustrates a dispenser 301 featuring: a cap 305 with a
stem 308; a cap housing 322 with an anterior opening 302 and a lever 307
protruding therefrom while adjacent to a slit 311; a body 303 with a
posterior opening 304; and a plunger 309. The identified components are
assembled into a dispenser 301 that operates in the same general manner
as described above in connection with the earlier embodiments.
Specifically, an axial force applied to the butt of the plunger 309
preferably opens the cap 305 to expose the anterior opening 302, shifts
internal components within the dispenser until the dispenser is locked
open and the lever 307 becomes an activated reversion means, and drives
the applicator 318 therethrough whereby a contained substance may be
transferred to a target. As discussed below, the primary difference
between the dispenser 301 and the earlier disclosed dispensers is that
the presently disclosed dispenser 301 is particularly adapted to dispense
substances that are less viscous, such as lacquers or stains (e.g., lip
stains).

[0113] FIG. 14A and 14B respectively depict cross-sections of a closed and
open dispenser 301 (because the figures are depicted in cross section, a
detailed view of the components may be seen in the exploded view of the
dispenser 301, FIG. 15). FIGS. 14A and 14B depict the components of the
dispenser 301, namely: the cap 305; the cap shoots 310; the press 324;
the cap housing 322; the body 303; the lever 307, with an edge 312 and
slit 311; the spring 319; the spring stop 320; the cap shoots 310; the
applicator 318; the shaft 315; the slot 316; and the plunger cavity 308
with a slot 316. In terms of opening and closing the dispenser, the cap
housing 322, the cap 305, cap shoots 310, body 301, spring stop 320,
spring 319, lever, and nub generally operate as disclosed above in
connection with the earlier dispenser embodiments, as will readily be
understood by those of skill in the art. However, unlike the earlier
embodiments, the dispenser 301 preferably provides a contained substance
to the applicator 318 via continual saturation of the applicator 318 with
substance (whether by absorption therein, by capillary action
therethrough, or by like phenomena) rather than the application of
pressure to force a substance through a shaft. More specifically,
referring to FIG. 14A and 14B, an applicator 318 is disposed within a
shaft 315 and extends into the plunger cavity 308 which is capable of
containing a substance. Do to the physical properties of the applicator,
the contained substance, and/or possibly gravity, the substance is driven
through the applicator 318 whereby the applicator 318, when exposed as in
FIG. 14B, may be directed to a target for selective transfer of the
substance thereto.

[0114] FIG. 15 is an exploded view of the dispenser 301 depicted in the
figures. FIG. 15 is also an inventory of parts, and a construction
diagram for the dispenser 301. The components generally fit together by
following the dashed line from the top left to the bottom right of the
FIG. 15. More specifically, the applicator may be constructed as follows:
(1) a substance 500 may be deposited into the plunger cavity 309; (2) the
applicator 315 may be disposed within the plunger 309 to seal the plunger
cavity 308 (B to B'); (3) the plunger and applicator 315 assembly may be
inserted into the posterior opening 304 of the body 302 (C to C'); (4)
the cap 305, cap shoot 310, and cap press 324 component may be installed
on the cap housing 322 (D to D') whereby the stem 313 is pivotably
attached thereto (E to E'); (5) the spring stop 320 may be inserted into
the cap housing 322 (F to F'); (6) the spring 319 may be provided to the
cap housing 322 (G to G') whereby the spring stop 320 and spring 319
interface (H to H') therein; (7) the body 303, and components assembled
thereto, may be inserted into the cap housing 322 (I to I') whereby the
lever 307 extends from the cap housing 322 (J to J'), the reservoir body
327 inserts into and receives the spring 319 (K to K', K' to K''); and
the cap press 324 couples to the plunger 309 (L to L'); and, (13) the
dispenser 301 may be opened as discussed above, and the applicator 318
may be provided to the shaft 315 (M to M') through the exposed anterior
opening 302 of the dispenser 301.

[0115] After contained substance stock is sufficiently diminished by
dispenser 301 use, the dispenser 301 may be disposed of or replenished
with substance. If replenishment of substance is desired, usually the
internal components are reset accordingly and the chamber re-stocked with
substance. This application contemplates that a dispenser 301, and
reservoir, may be either disposable or refillable.

[0116] The figures depict the dispenser 301 with a rigid but hollow
tubular body 303, a rigid but hollow cylindrical plunger 309, and other
components of various shapes and relative sizes. However, the body 303
and plunger 303 need not be tubular or cylindrical but may be any shape
seen fit by a person skilled in the applicable art. In addition to
cylinders, other shapes, including, but not limited to squared, polygonal
shapes, may be employed. Similarly, the various components shape and
relative size may also be so modified. For example, a dispenser 301
depicted by the figures may have the general appearance of a right
cylinder, but the general appearance may also be that of any
three-dimensional object.

[0117] The materials suitable for forming the dispenser 301 and its
components will vary depending on the physical properties of the
substance contained, and the nature of the expected dispenser 301 use.
The proper combination of materials for contained substance will be
readily apparent to those skilled in the art. Keeping that in mind, the
components of a dispenser 301 may be formed using a variety of preferable
materials, including but not limited to metals, alloys, composites,
woods, and a variety of hard plastics including but not limited to
high-density polyethylene, polypropylenes, PVC, and other materials that
will be appreciated by those skilled in the art.

[0118] The materials suitable for use in the applicator may preferably be
of porous or fibrous composition. For example, materials suitable for use
may be selected from, but should not be limited to, felt or nylon. Those
of skill in the art will know well the materials suitable for
construction of an applicator 318.

[0119] FIGS. 16, 17, 18 and 19 illustrate another embodiment of a cap 405,
cap shoot 410, press 424, and spring stop 420. Specifically, FIGS. 16,
17, 18 and 19 respectively illustrate a perspective view of a closed cap
405 and spring stop 420, a perspective view of an open cap 405 and spring
stop 420, a side view of a closed cap 405 and spring stop 420, and a side
view of an open cap 405 and spring stop 406. Unlike the embodiments
disclosed above, the cap 405 of the present embodiment may be hingedly
constructed to the spring stop 420 with the cap shoots 410 and cap press
assembled thereto. Operably, compression of the spring 419 forces the cap
away from the spring stop 420 in a similar manner to the earlier
embodiments.

[0120] FIGS. 20, 21, 22 and 23 illustrate another embodiment of a cap 505,
chords 510, press 524, and spring stop 520. Specifically, FIGS. 20, 21,
22 and 23 respectively illustrate a perspective view of a closed cap 505
and spring stop 520, a perspective view of an open cap 505 and spring
stop 520, a side view of a closed cap 505 and spring stop 520, and a side
view of an open cap 505 and spring stop 506. Unlike the embodiments
disclosed above, the cap 505 of the present embodiment may be hingedly
constructed to the spring stop 520 with the cables 510 and cap press 524
assembled thereto. Operably, compression of the spring 519 drives the
press 524 toward the spring stop 520 and slackens the cables 510 whereby
the cap 505 may be removed from the seal. When installed in a dispenser,
an applicator may be moved to contact the cap 505 whereby the cap 505
moves off plain from the spring stop 520 so that the applicator may exit
the dispenser unobstructedly.

[0121] It should be noted that in such dispenser embodiments, the
mechanisms for opening the cap may vary according to the design of the
dispenser. For instance, regarding the earlier disclosed dispensers 101,
201, and 301 any embodiment could be fitted with a cap press 424 whereby
the cap 405 would open and close in a manner that is similar to that
disclosed in reference to FIGS. 1-15. Further, the cap 505 may be molded
to the spring stop 520 whereby the cap 505, in conjunction with the
cables 510 would operate to close the dispenser 101, 201, 301 in a manner
similar to that disclosed by US. Pub. Pat. App. Nos. 20090245919
(published Oct. 1, 2009) and 20080175648 (published Jul. 24, 2008).

[0122] It should be noted that FIGS. 1 through 23 and the associated
description are of illustrative importance only. In other words, the
depiction and descriptions of the present invention should not be
construed as limiting of the subject matter in this application. For
example, the cap and spring stop need not necessarily form a seal.
Additional modifications may become apparent to one skilled in the art
after reading this disclosure.
